Working Principle of ERZ-E11E821

The ERZ-E11E821 is a type of varistor (also known as a metal-oxide varistor or a voltage-dependent resistor). It is comprised of zinc oxide particles that are sintered together in a ceramic matrix. When the voltage applied to it exceeds a certain threshold (known as the "clamping voltage"), the varistor begins to conduct and can limit the amount of current that flows. It acts like a resistor with varying resistance depending on the applied voltage.

When an overvoltage occurs, the current is diverted from the device being protected to the varistor, which then limits the current flow. This prevents the device from being damaged by the overvoltage. The ERZ-E11E821 has high thermal stability and minimal power loss, making it a suitable varistor for a wide range of applications.
